Madison rolls a number cube whose sides are numbered 1 through 6. she rolls the cube 40 times to determine if the cube is fair. she records the results of each roll in the dot plot to determine if the data-generating process is fair. which statement is true?

Fortunately, I've encountered this problem in class. 

These are the statements:

a.) The process is fair because the distribution is bell-shaped.
b.) The process seems unfair because 1 and 6 are unlikely.
c.) The process seems unfair because there is a gap
d.) The process seems fair because the distribution is evenly spread.

The answer for that is most likely letter C. The process seems unfair because there is a gap.

Below is an attached figure.

It will be a whole number.
